Abstract

PURPOSE:To execute color recording with high quality by setting position films for three primary colors with a monochromatic thermal transfer device, exposing successively photosenstitive paper by using the three position films and pressurizing the paper to color the paper. CONSTITUTION:The signal inputted from an RGB signal input part 29 is converted to the three color signals; yellow, magenta and cyan from the three primary colors of light in a color processing part 30. The signals for one image plane are stored into a memory 31 and are read out of the memory. The signals by each color are fed to a thermal transferring and recording part 32 where the thermal transfer of a mark for positioning and a positive image is executed and a positive film 7 for exposing is obtd. A white light source 12 is lighted up for the specified time to execute exposure in the yellow region of a filter 10 when the film 7 is fed until the mark thereof is detected by a sensor 18. The exposure is in succession executed similarly with the magenta and cyan as well. The special photosensitive paper 9 is pressurized and fed by pressing rollers 15, 16 by which the unexposed capsules are broken and the dye is emitted to color the color forming layer. The color recording is thus executed.
